VS

Radeon HD 5750 1GB vs Radeon HD 6750 1GB

Intro

The Radeon HD 5750 1GB features core clock speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 720(144x5) SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Compare that to the Radeon HD 6750 1GB, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this model. It features 720 SPUs along with 36 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon HD 5750 1GB should theoretically perform a small bit faster than the Radeon HD 6750 1GB in general. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon HD 6750 1GB 64000 MB/sec
Difference: 9600 (15%)

Texel Rate

The Radeon HD 6750 1GB will be a bit (more or less 4%) faster with regards to texture filtering than the Radeon HD 5750 1GB. (explain)

Radeon HD 6750 1GB 26100 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 900 (4%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is superior to the Radeon HD 5750 1GB, but not by far. (explain)

Radeon HD 6750 1GB 11600 Mpixels/sec
Radeon HD 5750 1GB 11200 Mpixels/sec
Difference: 400 (4%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
